My son experienced his vision turning upside down briefly then correcting itself and hallucinations (which he described in detail). Luckily he wasn't too freaked out by it.
Has anyone else experienced this, new one on me.
Update 17/9:
Still experiencing symptoms, had GP appt (whose examination was thorough) and although nothing found, he spoke direct to Hospital and my son has been referred to see a Consultant at the Hospital this Thurs.
